Professional Pinion Depth Accuracy

The GM 8.5in 10-bolt rear end is a staple in performance applications, and maintaining it requires absolute precision. The Ratech Pinion Depth Setting Tool is engineered to provide the accuracy needed to set your pinion depth correctly during a gear swap or differential rebuild. This aluminum fixture is designed to fit the 8.5in GM housing perfectly, allowing for quick and reliable measurements.

Key Benefits for Gear Installers

  • High-precision aluminum construction ensures stability and accuracy
  • Specifically calibrated for GM 8.5in 10-bolt applications
  • Simplifies the complex task of pinion depth adjustment
  • Helps achieve the ideal gear contact pattern for maximum strength
  • Reduces the risk of gear noise and premature wear

Setting up a ring and pinion set is a delicate balance of measurements. If your pinion depth is off, even by a few thousandths of an inch, it can lead to gear whine or catastrophic failure under load. This tool allows you to measure and adjust with confidence, ensuring that your gear set is positioned exactly where the manufacturer intended. Whether you are building a street cruiser or a high-performance track car, this tool is a must-have for any serious mechanic. Get the precision you need for your next build at GGCRACING.
